How to Fix a Mistake on Your Cambodia e-Arrival Card After Submitting (US Travelers)

The fix: submit a fresh, corrected card

Because there is no dependable self-service edit on a card you have already submitted, the reliable fix for a high-stakes error is to fill out a new card with the corrected details and submit it. This is lighter than it sounds — the card is only 14 fields and you already have everything in front of you. The new card generates its own confirmation and QR code, and that is the one you carry to the kiosk. Set the old screenshot aside so you do not present it by reflex, and keep a single clean copy of the corrected card on your phone, ideally with a printout.

1. 1
   Confirm you are in the window

   The card must be filed within the 7 days before you arrive, so make sure that window is open before you start the corrected submission.

2. 2
   File a fresh card

   Fill out all 14 fields again with the corrected details — there is no reliable edit button on a card you already submitted.

3. 3
   Fix the high-stakes fields exactly

   Match your name and passport number to your US passport bio page, and enter the final flight leg into Cambodia and the correct arrival date.

4. 4
   Save the new QR code

   The corrected card generates its own confirmation and QR code — that new one is what the officer scans at the kiosk.

5. 5
   Retire the old screenshot

   Delete or set aside the wrong card so you do not present it by reflex, and keep one clean copy of the corrected card on your phone plus a printout.

Timing is on your side. The card has to be filed inside the 7 days before you arrive, and as long as you are still in that window you can lodge a fresh corrected card without any trouble. The only real pressure is if you submitted very early and the window has not opened yet — in which case wait until you are inside the 7 days, then file the correct card once.

To confirm your corrected submission actually went through and find the QR code to save, our guide to checking your Cambodia e-Arrival Card status walks through exactly where the confirmation lives.

Fixing the four mistakes US travelers make most

Four errors account for almost every flagged US-filed card. Here is what each one looks like and how to make it right, in order of how often we see it.

The arrival date in the wrong format

This is the runaway leader. The form reads day-month-year in places, and Americans default to month-day-year out of habit, so 06/07 typed as "July 6th" gets read as June 7th and your arrival date lands a month off. The fix is mechanical: file a corrected card, and this time use the date picker rather than free-typing the slashes, then sanity-check the result against your flight confirmation. If the screen shows a different day than your ticket, you are still in the trap — adjust before you submit.

The wrong flight number

The second classic is entering the long-haul flight out of the United States instead of the final leg that actually lands in Cambodia. If you fly Los Angeles to Seoul to Phnom Penh, the flight number on the card is the Seoul-to-Phnom-Penh hop, not the LAX-to-Seoul one. Pull your booking, find the leg whose destination is your Cambodian airport, and resubmit with that flight number — this is the field Immigration cross-checks against the manifest.

A name that does not match the passport

A dropped middle name, a nickname instead of the legal first name, or a married name that is not on the passport yet — any of these creates a mismatch between the card, your eVisa, and the document you hand over. Resubmit with your name exactly as printed on your US passport bio page, character for character, including the middle name if it is there. If the same mismatch crept into your visa too, our guide to e-Arrival and US passport name mismatches walks through getting both to agree.

A transposed passport number

A single swapped or mistyped character in the passport number is easy to do and easy to miss. Open your passport to the bio page, read the number digit by digit, and resubmit. This one is quick to verify and quick to fix, but because the number is matched against your eVisa and the passport itself, it is firmly in the fix-it column.

If you only catch it at the airport

Say you do not notice the mistake until you are already at the gate, or worse, standing at the arrivals kiosk in Cambodia. It is not a disaster, but it is the version of this problem you most want to avoid, because you are now solving it under time pressure with airport Wi-Fi.

If you spot it before you board, the move is the same as at home: submit a corrected card from your phone while you still have a solid connection, save the new QR code offline, and carry that one — do it in the lounge, not while the agent is scanning boarding passes. If you only realize at the kiosk in Cambodia, stay calm and tell the officer. The e-Arrival Card is an arrival declaration, and a single wrong field is routine for the desk to handle: the realistic outcome is a short delay, not a denied entry, especially when your eVisa and passport are in order.

If your mistake also touched the visa itself rather than just the arrival card, our guide to fixing wrong information on a Cambodia eVisa for US citizens covers that side of the correction.

Getting it right the first time — and where it sits next to your eVisa

Run a 30-second review before you ever hit submit, and you skip this whole article next time. Name matches the passport exactly, middle name included. Passport number has no transposed digits. Flight number is the final leg into Cambodia, not the US departure. Arrival date reads correctly in day-month-year and matches your ticket. Those four checks catch every mistake that actually matters at the kiosk.

Keep the order of operations straight too. The eVisa is the big step you do first, weeks ahead — Tourist $80 USD or Business $90 USD, both approved in 3 business days and delivered as a printable PDF by email. The e-Arrival Card is the light step you do last, inside the 7 days before you fly. The Cambodia visa for US citizens pillar covers requirements, costs, and timing in one place, and our step-by-step e-Arrival walkthrough shows you the form before you fill it. And if you would rather not do any of this from memory at 2 a.m. before a long-haul flight, you can file a verified e-Arrival Card through us for $5 USD instead.

Next steps and related reading for US travelers: file your verified e-Arrival Card when your flight is locked in, walk the full e-Arrival form field by field if you want to see it first, check your e-Arrival Card status to confirm the corrected version went through, and apply for your Cambodia eVisa if you still need the visa itself.
